on a wear sleeve 29 that is clamped to the i hub 2l, both of. these sleeves being preferably made in halves, as best shown in Fig. 5. A cone 30 is formed integral with the groored sleeve and rides upon the free ends of the plates upon shifting of the sleeve longitlulinnlly with respect to the axle section l1. Upon the cone being moved toward the plates, the latter will be depressed with resultant application of the locking pins to the piiiionsA Upon the cone being moved away from the plates, the springs which control the latter, immediately move the latter outwardly with resultant disengagement of the pins from the pinions. Y

For shifting the cone above described, a shift lever 31 is passed through an opening in the differential gear casing 32 and is terminally forked as shown at 33 to ride in the groove of the sleeve 28. This lever may be operatively connected in any preferred manner to an operating lever within convenient reach cf the drivers seat upon the automobile. It is to be understood that any suitable mechanism for shifting the cone may be employed, other than that illustrated, without departing from the spirit of the invention.

From the above description taken in connection lwith the accompanying drawings, it will be apparent that I have provided an extremely simple, strong and durable mechanism for locking the pinions of a diffe-rential gear against rotation whereby to lock the axle section together for simultaneous rotation when desired.

wheel having a hub journaled on both of idea/isiV seid axle sections, bevel gear wheels secured l on the adjacent ends of said axle sections within said hub, intermediate bevel pinions journaled on said hub and meshing with said bevel gear wheels, of a hinged plate on said hub above one pinion, a pin carried by said plate projecting through said hub and adapted to engage in an opening in the related pinion, a means for normally holding said plate at its outer limit of movement and the pin disengaged from said pinion, and means for depressing said plate against the action of the holding means to engage said pin with said pinion and lock said pinionA against rotation on said hub.

2. The combination with the sectional axle of an automobile, of a driven gear wheel having a hub journaled on both of said axle sections, bevel vear wheels secured on the adjacent ends o said `axle sections within said hub, intermediate bevel pinions journaled on said hub and meshing with said bevel gear wheels, of a hinged plateon the exterior of said hub above one pinion, a pin carried by said plate adapted to engage in an opening in said pinion and lock said pinion against rotation, a spring normally holding said plate at its outer limit of movement and said pin disengaged 4from said inion,and a shiftable cone embracing said lub and riding upon said plate whereby to depress said plate and engage said pin with said pinion.

In testimony whereof, I affix my signature, in the presence of two witnesses.
